Abstract :
Do you suspect that they´re talking behind your back ¿ and you can´t hear what they´re saying? Now you can give yourself a comprehensive and relatively inexpensive hearing test in a matter of minutes, complete with a hard-copy printout of the results, by the simple push of a button. All you need for the audiogram is an instrument developed by Derek McClure of Alberta Systems Development Group, Wetaskiwin, Alta., Canada, and you´re on your way.
